I can confirm that PIX-LR works only with PIX-E video recorders series. If you need Zoom alternatives in Sound Devices (i.e. standalone audio only recorders) there are the wonderful 702 and 702T (in my opinion, the best 2-channels field recorders in all over the world!) Anyway - again, in my opinion - PIX-LR itself is a very good reason to prefer PIX-E recorders series to Atomos devices (probably same video quality - we will see - but not the same audio quality).
